When Permitted Development Does Not Apply

What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply covering thermal performance (Part L, minimum U-value), security standards (Part Q, PAS 24:2022), safety glazing if the door contains glass panels (Part K), and accessibility (Part M for new dwellings). A FENSA or CERTASS-registered installer can self-certify compliance.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Tonbridge and Malling building control or use an approved inspector.

What Happens If I Build Without Permission?
